Abstract (en)
[origin: US2017033810A1] A communication system comprises a signal generator, polarizer, signal combiner, transmitter, positioning device, and controller. The signal generator converts first and second received data streams into respective first and second orthogonal linearly polarized signals. The polarizer is at a first rotation angle and converts first and second orthogonal linearly polarized signals into, respectively, a first right-hand-circularly polarized (RHCP) signal and first left-hand circularly polarized (LHCP) signal, which are combined in signal combiner into a signal sent by transmitter to a receiver. The positioning device adjusts the first rotation angle to substantially increase isolation between third and fourth orthogonal linearly polarized signals at the receiver. The controller performs the real-time analysis of transmission loss and directs the positioning device to adjust the first rotation angle.
